Windows has two ways to use thread local storage. The most efficient
is using __declspec(thread), but that does not work properly when
used in a .dll that is loaded at runtime, after program load. So for
libmysql.dll and libmysqld.dll we define USE_TLS in order to use the
TlsXxx() API instead, which works in all cases.
